Reporting activities for the oxygen evolution reaction: Do we compare apples to apples?

TL;DR

This paper evaluates current benchmarking protocols for the oxygen evolution reaction, highlighting inconsistencies and proposing improvements to ensure more comparable and reliable data in energy storage research.

Contribution

It critically assesses existing OER benchmarking methods and offers recommendations for standardized protocols to enhance data comparability.

Findings

Current protocols vary significantly, leading to inconsistent data.

Standardization is needed for reliable comparison across studies.

Proposed guidelines aim to improve benchmarking consistency.

Abstract

The oxygen evolution reaction (OER) is a key enabler of sustainable chemical energy storage. Here, the author assesses the current status of protocols for benchmarking the OER in materials- and device-centered investigations and makes suggestions for more comparable data.
